Z 1o all whom t may concern.'

Be it known that I, JOHN C. KIs'rLE'R,

v a citizen of the United States, residing `at Clinton, in the county of Henry and State of Missouri, have invented certain new and useful Improvements inTire-Saving Jacks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in tire saving jacks.

The primary object of the invention is to provide a hoisting jack for sustaining the weight of a vehicle while standing in `storage or in a garage, thus relieving the weight thereof from the pneumatic tires of the vehicle. v

Another object of the invention is to provide a jack of this character, the raising means of which include an operating lever which is journaled to the base in order to allow it to be operated from substantially iny position relative to the side of the venc e.

vide a device of this character which will be of simple, strong and economical construction, and one which will be efficient and reliable in operation4 and well adapted to the purpose for which it is designed.

With these and other objects in View, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of the specifications, and in which similar reference characters designate like parts throughout the several views-Figure 1 is a side elevation of a device constructed in accordance with this invention; Fig. 2 is a central vertical longitudinal sectional view of the same; Fig. 3 is a vertical sectional view taken on the plane of the line 3-3 of Fig. 2; Fig. 4 is a horizontal sectional view taken on the plane of the line 4-4 of Fig. 2; and Fig. 5 is a similar view taken on the plane of the line 5 5 of Fig. 2.

The preferred form of the present invention comprises a base 1, an upright standard 2, and means for revolubly mounting the standard to the base. This base 1 is here shown as being of rectangular configuration and provided on its upper side with a suitable circular recess 3. Extending upwardly from the opposite ends of the base 1 is a pair-of converging flat'metallic braces 4, the lower ends of which are provided with laterally extending feet 5 which are secured by suitable bolts or screws 6 to said base. The upper ends of the braces 4 are integrally united by a portion 8, and secured in any suitable manner, here shown by means of rivets 7, to the portion 8 is a circular horizontal collar 9, the latter being arranged in vertical alinement with the recess 3 and Abeing made from a flat strip of sheet metal,

as shown.

The standard 2 of this improved jack is made from a single piece of metal, and is substantially U-shaped in cross section. EX- tending from the upper and lower ends of the standard 2 are tubular extensions 10 and 11 respectivelv, the upper extension 10 heing journaled in the aforesaid collar 9, while the lower extension 1l is received and similarly journaled in the aforesaid recess 3 in the base l. Thus it will be readily understood that the standard 2 is revolubly mounted with respect to the base 1. Another object of the invention is to pro- Pivoted at l2 in the lower `end of the standard 2 and between the sides thereof is a tubular link 13, the upper end of which is provided with a pair of spaced pivot ears 14 between which is disposed and pivotally connected the intermediate portion of an operating lever 15. Slidably mounted in the upper extension l0 of the standard 2 is a tubular lifting plunger 16, the lower end of which is bifurcated and pivoted to the eX- treme inner end of the lever l5. The lever 15 is olfset laterally at a point spaced from the pivoted inner end thereof as is clearly shown in the drawings, the free end thereof extending in substantially parallel relation to said pivoted inner end to provide a suitable handle by which it is operated. This tubular' lifting plunger 16 is internally threaded for the reception of an externally threaded shank 17 which depends from the lower side of a substantially rectangular -flat metal supporting plate 18. Secured to the upper side of this plate 18 in any suitable Inanner, is a rubber or other suitable cushion 19, upon which the hub of the vehicle is adapted to rest. By this arrangement, it may be readily seen that vertical adjustment of the metal plate may be readily and easily accomplished.

The device is particularly designed to be used as a lifting ack for relieving the weight of an automobile or other vehicle from the tires thereof. When applying thel device to use, the outer end of the' lever I5 is `raised kand the rectangular metal plate 1 8 is adjusted to substantially the height'o'f the hub of the automobilefrom theground.A By a downward thrust upon the outer end of the lever, the plunger 16 is raised and the upper end of the link 18 is moved inwardly between the sides ofthe standard 2.- It will loe thus seen that when in this position, the link 13 and the inner arm of the lever 15 .are f arranged in substantially longitudinal and vertical alinement with the lifting plunger 16, and as the pivot connecting the yupper end of the link 13 and the intermediate portion of the'lever 15 is passed a trifle 'beyond dead center,' the jack will be locked in its `raised position. v

v In the vevent that the garage is very narrow and there would not be room 1n which tol swing'the operating lever 15 to its upward'position, provided, however, that the vsaine 'were extending laterally of the vehicle,the standard l2 may be easily and conveniently revolved inlthe recess 3 and collar '9, thereby allowing the lever to extend ina direction lsubstantially longitudinally ofthe vehicle.- This, as will be readily understood, isav very convenient feature of the invention.

VFromY the foregoing description, taken 'in connection` with vthe accompanying drawings, the operation and advantages ofthe invention will be readily'understood'without amore extended explanation.

As various changes in' form andf propor- Go'pies of 'this patent "maydbe obtained for ;'tion and the minor details of construction maybe resorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and described other than that set forth inth'e appended claim.

saidbraces being integrally united at their upperends Aand belng- Iirmlj.7 secured to one `side of sald collar, an upright standard made from a single piece of sheet metal and being substantially U-shaped in cross section and having tubular extensions at the upper and lower ends thereof, the extension at the lower end of said standard being disposed and `journaled in the recess in said base, the extension at the upperl end of said standard extending through and being journaled in said collar, a lifting plunger slidablein the glast referred to extension, and jack `means for raising and lowering said plunger. f f

Inj testimony whereof I have hereunto set myihand in presence of two subscribingwitnesses.
